CD4049UB, CD4050B Semiconductor August 1998 File Number 926.2 CMOS Hex Buffer/Converters The Harris CD4049UB and CD4050B are inverting and non-inverting hex buffers, respectively, and feature logiclevel conversion using only one supply voltage (VCC). The input-signal high level (VIH) can exceed the VCC supply voltage when these devices are used for logic-level conversions. These devices are intended for use as CMOS to DTL/TTL converters and can drive directly two DTL/TTL loads. (VCC = 5V, VOL ≤ 0.4V, and IOL ≥ 3.3mA.) Features • CD4049UB Inverting • CD4050B Non-Inverting • High Sink Current for Driving 2 TTL Loads • High-To-Low Level Logic Conversion • 100% Tested for Quiescent Current at 20V • Maximum Input Current of 1µA at 18V Over Full Package Temperature Range; 10 [ ... ]
